• (2022) A Horse Owner’s Guide to Pasture-associated Laminitis The key to preventing laminitis in your horses is to regulate their time grazing on grass high in nonstructural carbohydrates. Inadequate exercise is another cause of this painful hoof condition.
• (2021) Pasture & Grazing Management in the Northwest The comprehensive resource for anyone who manages livestock on pastures in the Northwest, this book offers pasture managers information and tools to enable their pastures and their livestock to reach their maximum production potentials. Seventeen chapters proceed from planning to budgeting. Black and white with color plates.
  
• (2021) Forage Response to Irrigation and Wheel-line Irrigation Management Mylen Bohle, OSU Extension Agronomist, discusses how forages respond to irrigation and drought on a biological level, and how the biological behaviors translate to efficient irrigation management
• (2021) AgriMet and Irrigation Water Management OSU Extension Agronomist, Mylen Bohle reviews the AgriMet system, which allows growers to better understand their crops actual water use and develop sophisticated irrigation scheduling plans
• (2018) Plants Causing Physical Injury in Pastures Many plants have characteristic that can cause injury to grazing animals. Some grasses can be palatable when young, but can cause injury to the nose, eyes, mouth and ears of grazing animals when plants mature with long awns.
• (2018) Plants Causing Irritation in Pastures Plants in this group contain compounds that may irritate an animal's digestive tract, mouth or skin if consumed. These plants are not generally palatable and are typically avoided.
• (2018) Plants Affecting Cardiovascular Health in Pastures Cardiac glycosides are the most common toxin affecting cardiovascular health. Generally all parts of the plant are highly toxic and lethal if eaten in small quantities. However, animals typically will not readily eat these unpalatable plants, unless no other forage is available.
• (2018) Plants Causing Cyanide Poisoning in Pastures This group of plants contain cyanogenic glycosides that are converted to hydrogen cyanide or prussic acid when the plant cells are damaged. Chronic poisoning over time causes loss of nerve function while acute poisoning causes death.
• (2018) Plants Causing Organ Failure in Pastures This group of plants contain pyrrolizidine alkaloids which are the most common cause of liver damage, but also can cause kidney damage, heart failure, cancer and photosensitization. Animals typically will not readily eat plants with pyrrolizidine alkaloids, unless no other forage is available.
• (2018) Plants Causing Liver Disease & Sunlight Sensitivity in Pastures Plants causing liver disease and photosensitization (sensitivity to sunlight) are often grouped together, as photosensitivity is often a secondary symptom of liver disease cause by poisonous plants.
• (2018) Plants Causing Nitrate & Oxalate Poisoning in Pastures Some plants absorb excess nitrates or oxalates from the soil and store them in plant tissues. Toxicity problems can occur in animals which feed on these plants.
• (2020) Invertebrate Pest Management for Pacific Northwest Pastures
• (2019) Alfalfa soil fertility and fertilization requirements A productive alfalfa crop removes significant quantities of macronutrients and small amounts of micronutrients from the soil. A complete fertilizer program is essential to ensure a highly productive, long-lived stand.
• (1998) Oregon Forage Library The Oregon Forage Library is a collection of hay test results on hay grown around the state. An update to the library is currently in progress. It will contain hay test values found since this publication was written.
• (2018) Poisonous Plants Commonly Found in Pastures Pastures often contain weeds that are potentially dangerous to livestock. The toxic compounds in plants are usually a defense mechanism against predation and have a distinct, unpleasant odor or a bitter taste and are not preferentially grazed. Consumption of unpalatable plants will increase under some circumstances, primarily if other forage is not available. Understanding the dangers and various management strategies to control toxic plants will reduce the risk to your livestock.
• (2010) Pasture and Grazing Management in the Northwest This publication includes management tips and information on how to properly manage pastures in the Northwest.
• (2007) Irrigating pastures Irrigating pastures can provide livestock with nutrition long into summer. Learn to monitor soil moisture to determine when to irrigate and how much water to apply.
• (2010) Pasture and Grazing Management in the Northwest
• (2010) Irrigated Soft White Wheat (Eastern Oregon) Nutrient Management Guide
• (2009) Winter Grain Mite: A Fall and Winter Pest of Cereals and Grasses in Oregon
• (2002) Dryland Cropping Systems: Dryland Alfalfa
• (2007) Managing Small-Acreage Horse Farms in Central and Eastern Oregon
